摘　　要：目的:研究小花八角的化学成分。方法:采用多种色谱方法分离纯化,根据理化性质、核磁共振和质谱方法进行结构鉴定。结果:从醋酸乙酯部位分离得到7个化合物,鉴定为新大八角素(1),2-氧代-3,4-去氢氧化新大八角素(2),反式桂皮酸(3),3,3,′4,′5,7-五羟基黄烷(4),莽草酸(5),山柰酚(6),山柰酚-3-O-α-L-吡喃鼠李糖-(1→6)-β-D-吡喃葡萄糖苷(7)。结论:以上化合物均为首次从小花八角中分离得到。AIM： To study the chemical constituents of Illicium micranthum. METHODS： Various column chromatographic techniques were applied to isolation and purification and the structures were elucidated by NMR and MS. RESULTS： Seven compounds were isolated from the part of ethyl acetate and identified as Neomajucin （ 1 ） , 2-oxo-3,4-dehyhroxyneomajucin （2）, Transcinnamic acid （3）, 3, 3＇, 4＇, 5,7-pentahydroxyflavan （4）, Shikimic acid （5）, Kaempferol （ 6 ）, Kaempferol-3-O-α-L-rhamnopyranosyl-（ 1 →6 ） -β-D-glucopyranoside （ 7 ）. CONCLUSION： The above compounds are obtained from this plant for the first time.
